Add code tags and explain a bit about what the program is supposed to do. Simply put [ code ] and [ / code ] around your code and remove the spaces.

I need to convert this program to read from input file.
I know how to create the data file but I am strugling with how to code in fstream

The game shows a number in a square which tells you how many mines there are adjacent to that square. Each square has at most eight adjacent squares. The 4 × 4 field on the left contains two mines, each represented by a “*” character. If we represent the same field by the hint numbers described above, we end up with the field on the right:

*... *100 .... 2210 .*.. 1*10 .... 1110
The input will consist of an arbitrary number of fields. The first line of each field contains two integers n and m (0 < n, m ≤ 100) which stand for the number of lines and columns of the field, respectively. Each of the next n lines contains exactly m characters, representing the field.

Can someone help !!! Pls!!!
